Q:Is polyurethane TPV suitable for sealing products?
4 、 shell of battery and radio telephone and sheath of electronic transformer shell;5. Insulation layer and sheath of power cable of ship, mine, drilling platform, nuclear power station and other facilities.- traffic equipment1. Road and bridge expansion joints;2, road safety facilities, buffer anti-collision components;3, container sealing strip.
Q:Who knows, the country has a few sealing strip production enterprises are more concentrated place
Aluminum Alloy seal doors and windows, steel doors and windows, glass curtain wall seal sealant, container door seal and a door sponge rubber sealing strip, sealing tape, self-adhesive frozen door sealing strip, the doors of the glass slide, door trim, sponge sealing strips and retaining of the glass doors, glass windshield seal, fire seal flame retardant, pipe, tube, silicone tube, winding hose, water pipe, air pipe and oil pipe, automotive rubber seal, EPDM seal, with flexible sealing strip, sponge foaming adhesive tape, sealing tape, foam tape
Q:Classification of sealing strip by use
Y ring seals, piston seals, sometimes static sealsMechanical seals, pumps, turbines, high pressure vessels, compressors, agitation. A combination of different materials, including metal bellows seals, can be usedThe oil seal is sealed or sealed with other seals, and dustproofSplit slip ring seal, hydraulic turbine, steam turbine, multipurpose graphite, slip ringLabyrinth seal steam turbine, pump, compressor reciprocating, should be high speed, low speed do not useFloating ring seal pump and compressorCentrifugal seal and screw seal pumpThe magnetic fluid sealed compressor is only used in gas mediumTable 29.2-3 types and applications of dynamic sealsVacuum pressure (absolute pressure) /MPa (g) /MPa / C working temperature line speed of /m - S-1 / M - H-1 leakage rate using the term applicationPacking sealing 1.33 * 10-3, 31.38 -240 ~ 6002010~1000 - clean centrifugal pump, plunger pump, valve stem sealContact forming packing, extrusion type, 1.33 * 10-7, 98.07 -45 ~ 230100.001 ~ 1 ~ 0.16 months hydraulic cylinder, hydraulic cylinderLip type 1.33 x 10-9 0.1 to 10Rubber oil seal - 0.29 -30 ~ 150123~6 months bearing sealing and dust-proof
Q:How are ceramic and metal sealed joint?
For rotational motion, the rotary shaft lip seal ring should be used.If the metal is in the outside, in the ceramic, then rotating sealing lip can be directly sealed ceramic surface, because ceramic material is hard enough, wear; if it is metal on the inside, outside is ceramic, then do some processing on the metal surface, such as hard chrome plating, plating ceramic. Or the sleeve, and the shaft interference fit, hot installation, the surface should also be hardening treatment
Q:Aging test report of rubber sealThat is to say, rubber sealant is how anti-aging
The factors that cause rubber aging are:(a) oxygen, oxygen free radical chain reaction in rubber with rubber molecules, the molecular chain rupture or excessive crosslinking caused by rubber properties. The change of oxidation is one of the important reasons for the aging of rubber.(b) ozone, ozone chemical activity is much higher than the oxygen, more damaging, it is also the molecular chain was broken, but the effect of ozone on the rubber with rubber deformation and no different. As for the deformation of the rubber (mainly unsaturated rubber), and should be perpendicular to the direction of stress crack the so-called "ozone cracking"; effect on the deformation of the rubber, only surface oxide film without cracking.(c): heat temperature increase can cause rubber thermal cracking or thermal crosslinking. But the basic role of heat or activation. Improve the diffusion rate of oxygen activation and oxidation reaction, thus speeding up the rubber oxidation reaction speed, which is an aging aging phenomenon, heat and oxygen.(d) light: light is shorter, the greater the energy. The destructive effects of rubber from the high energy ultraviolet light can directly cause fracture and cross-linking of rubber chain, rubber due to absorb light energy and produce free radicals, trigger and accelerate the oxidation reaction. The ultraviolet light plays the role of heating. The other feature (light and heat effect) is its main in the rubber surface into. The gum content of high sample, both sides will appear net cracks, the so-called "light outer crack".
Q:Sealing type and specification of solenoid valve core
Noise reduction and decompression of the seat, and therefore used for flashing and other industrial and mining, the drawback is that the media can not be used for dirty areas.V- ball and eccentric rotary valve can be used in slurry and other impurities containing medium.
Q:Is the piston on the hydraulic cylinder sealed by shaft or by hole?
The piston of the hydraulic cylinder is sealed with a hole.Related profiles:1, hole seal.Application: it is used to seal the piston of hydraulic cylinder in reciprocating motion.
Q:Seal type of transformer oil tank
3., rubber seal material selection is improper, transformer if it is outdoor installation use environment, should choose ultraviolet resistant rubber. If you use a high temperature position, you should choose a high temperature resistant rubber, if used in contact with the transformer oil, you need to select oil resistant rubber.
Q:What's the function of the sealing ring?
Basic concepts of mechanical sealsThe mechanical seal is defined by at least a pair of end faces perpendicular to the axis of rotation of the fluid pressure and the elasticity of compensation organizations (or force) the role of the device and auxiliary seal with maintaining relative sliding postmerger and constitutes to prevent fluid leakage. The auxiliary seal of the compensating ring is metal bellows, and is called bellows mechanical seal.
Q:What are the basic parameters of the seal on the diagram?
Temperature: -40/+200Material: NBR/PTFE FKMMedium: hydraulic oil, flame retardant liquid, water and gas
